As soon as the software from Nvidia installed the most recent version of their driver update for my high-priced- priced graphics card, it started displaying artifacts and crashing. The diagnosis that the graphics processing unit (GPU) was broken was made official by the repair shop. After more than six weeks of providing facts and evidence that many other people were experiencing card damage from their 511.67 drivers, Nvidia refused to stand behind their defective driver and told me to look elsewhere. This was after I had provided them with facts and evidence that many other people were experiencing card damage from their drivers. A terrible company with a sham foundation for its operations.
